There’s a lot to be said about “XCOM: Enemy Unknown” for iOS, but none of it can be said without eventually mentioning the price.

Yes, “XCOM” is a $20 gaming app, in a world where $20 can also easily translate to owning 20 gaming apps. This will cause many people dismay, or even fits of laughter.

But I’m not going to talk about the price just yet. Instead I just want to focus on “XCOM.”

“XCOM” took the console and PC world by storm last year as gamers everywhere discovered the joy of running a worldwide alien defense organization, and commanding troops on the ground in tense and violent tactical operation scenarios. A revival of one of the most complicated and hardcore PC franchises of all time, “Enemy Unknown” somehow managed to find a way to maintain the things that made that series great, while also making the experience much more manageable and appealing to the more mainstream gaming market.

Of course the star of the game is its permadeath system. Much like last weeks “Sword and Glory” app, death is not only around every corner in “XCOM,” but when it happens you lose that soldier for good. This is made worse by how much you can customize a soldier to make them your own, and the hours you will inevitably spend leveling up your favorites. No matter how much time or effort you put into a character though, one false move and they are dead and gone.

It’s a punishing system to be sure, but it gives the game an element of tension that would be impossible without it. Every decision matters in “XCOM,” whether it be on the battlefield, or in the management mode when trying to determine what countries to aid (you can’t save them all) and what research to pursue in order to manufacture new items and weapons. Every moment in “XCOM” is spent making these tough decisions, and as such success and joy are found not in glorious moments of gratification, but just through mere survival, and a chain of little moments that make up your 30+ hour playtime.

A glorious moment of success is to be found, though, the minute you boot up the game and realize that this is indeed the entire “XCOM” experience (sans multiplayer) on a mobile device. Sure the graphics took a very slight hit, but this is compensated for by some nice touch controls that add to the feeling of being the “Commander” character the game casts you as. While playing this on an iPhone over an iPad is not the most welcoming of propositions, again it’s the fact it even exists in that format in a playable manner that deserves recognition.

Ultimately though, even though this is still every inch of the original 2012 game of the year candidate expertly ported by 2K to a potentially hostile format, it does come back to the price. While $20 spent well is a fair amount of money, the fact is that $20 for this game is a steal, considering it means you’re getting what is essentially a console game at about a third of the original price, to take with you wherever you go. The price is all a matter of perspective, and in an app world where a “Free” game can easily set you back around $20 when you consider in-app purchases (of which “XCOM” has none) and usually are not of this level of quality, you really have to call this a case of paying an appropriate price for what you get.

“XCOM” defied expectations last year and made most of its fans out of people who never played this type of strategy game before, much less the franchise. With any of the luck I do not have when I play this game (my guys die a lot), this mobile version will do the same as it’s a near-flawless port of that all-time great strategy experience.

So get ready to craft a virtual graveyard of fallen soldiers, start seeing Chryssalids in you nightmares, and get addicted to “XCOM” all over again as it’s not only a perfect port, but my app of the week.
